SERVICE WEAR FACTORS
SPEED - High speed accelerates wear. For longer service
life, keep speed as low as possible. Pump speeds above 900 R.P.M.
not recommended except for intermittent duty and pressures below
100 p.s.i.
PRESSURE - High pressure accelerates wear. For longer
service life keep pressure as low as possible.
LIQUID TEMPERATURE - High temperature accelerates
wear. Keep as close to room temperature as possible.
LIQUID CONTAMINATION - Impurities like fine abrasive
silt or sand accelerate wear. Keep liquid as clean as possible.
LIQUID LUBRICITY - Lubricants increase service life many
fold. Use lubricant additives whenever possible.
Note: Dotted lines(---) recommended for intermittent duty only
due to accelerated wear at higher speeds and pressures.
NOISE - Large gear pumps are inherently noisy due to metal to
metal gear contact. Make installations far removed from offices or other
relatively quiet people areas. Some noise reduction can be realized by
lowering pump speed and use of isolation mounts and lines, usually the
small amount of noise reduction achieved does not justify the effort and
expense.
DRIVE & ALIGNMENT- Direct drive is the recommended drive
arrangement. This pump is suitable for belt drive applications without
needing pillow block bearings to achieve acceptable pump life. Correct
alignment is absolutely essential for satisfactory pump life. Recheck alignment after piping has been connected to the pump. Electric clutch ver sions available.
SEAL CONVERSION KITS
Seal conversion kits, illustrated (on back) are designed for quick
removal and replacement. In each case, seal housings are fastened to
pump bodies by means of 2 bolts, item 13. IMPORTANT - before attempt ing to remove a seal housing containing seal components by sliding them
off the pump shaft, be sure to unlock the 2 set screws locking the ball
bearing inner race to the pump shaft. The ball bearing is identified as item
20. Also, before attempting to slide the seal housing from the pump shaft,
remove all burrs, scale, and projections that could be formed by fretting
corrosion.
